Shearer, who only featured 20 times due to injury for the Millers throughout the season, had won double promotions under boss Steve Evans at Crawley.
And he told todays Star that Saturdays runners up clinching win over Aldershot, which sparked wild celebrations, was the best of the three.
“To complete a hat-trick of promotions is fantastic. This is the most special one of my career. The pitch invasion before the game had finished was unbelievable; that was mental! I think it just showed how much it meant to everybody involved at the club.
“The whole league has been inconsistent this year and the points tally tells you that. At Crawley last season, we finished third with 84 points and we only got 79 this year."
He added: “We thought we had thrown it away when we lost at Morecambe. I don’t think anyone would have predicted we would go on this run (five straight wins).
“The biggest result and night for me was at Bradford. I will remember that for years.”
